fix building list of args for execution

Before:
arg name and value were 'joined' together and pushed to the list of args as a single arg E.g. "-0 0" causing exteplayer3 to incorrectly interpret them

After:
arg name and value are pushed to the args list separatedly E.g. "-0" "0" enabling exteplayer3 to work properly
